Heartwood

Vedclass · Answer

(A) As a tree grows older,the secondary xylem in the central or innermost region of the stem becomes dark brown due to the deposition of organic compounds like tannins,resins,oils,gums,aromatic substances,and essential oils. This region is known as $Heartwood$ or $Duramen$. The heartwood does not conduct water but provides mechanical support to the stem. The peripheral region of the secondary xylem,which is lighter in color and involved in the conduction of water and minerals,is called $Sapwood$ or $Alburnum$. As the tree ages,the amount of heartwood increases significantly because more and more sapwood is converted into heartwood over time.
